Chapter 5205

At this moment, the altar suddenly vibrated violently, the black magic core burst out with dazzling light, and the runes around the altar quickly melted like ice and snow.

A huge pressure came from under the altar, and the entire underground palace began to shake, as if something was about to break out of the ground.

“Oh no! The seal is about to be broken!”

Kai’s face changed drastically. “Youyue probably knew this would happen a long time ago. She asked us to come and get the magic core just to make us break the seal!”

A deafening roar came from under the altar, and huge cracks appeared on the ground. Black demonic energy gushed out from the cracks and condensed into a demonic shadow dozens of feet tall.

The demon shadow holds a huge axe and has a ferocious face. He is the sealed ancient demon general!

“Hahahaha… I’m finally out!”

The demon general’s voice exploded like thunder, causing pain in the two men’s eardrums. “It’s been two thousand eight hundred years, and I didn’t expect that someone would dare to open this seal!”

Hu Mazi’s face turned pale, and the hand holding the clan leader’s token trembled slightly: “This is… the ancient demon general? His aura is so strong!”

Kai protected Hu Mazi behind him, and the spiritual power in his body burst out without reservation. The Dragon Slaying Sword made a buzzing sound and exuded a sharp sword energy: “It has just broken the seal and its strength has not yet fully recovered. We still have a chance!”

The demon general’s gaze fell on Kai, and a trace of disdain flashed in his eyes: “You are just a human cultivator, and you dare to be so presumptuous in front of me? Die before me!”

It swung its giant axe and chopped towards the two of them. The black axe blade, with its earth-shattering momentum, tore apart the air in the entire underground palace.

Kai did not dare to be careless. He pulled Hu Mazi and jumped to avoid the axe.

The axe blade fell to the ground with a loud bang, and a bottomless chasm was created in the ground, with gravel flying everywhere.

“Senior, this guy is out. You attach yourself to me and kill him right away. He’s not as awesome as you!”

Kai hurriedly called upon the Red Cloud Demon Lord to possess him, and then killed the demon general.

But Kai shouted for a long time, but Demon Lord Chiyun seemed not to hear him!

“F*ck, pretending to be dead…”

“Master Hu, find a way to reinforce the seal again!” Kai had no choice but to ask Hu Mazi to reinforce it, while he rushed towards the demon general with the Dragon Slaying Sword in hand, “I’ll hold it back!”

He knew that it was impossible to defeat the ancient demon general with just the strength of two people, and the only way to have a chance of survival was to seal it again.

Hu Mazi also reacted and immediately took out the talisman paper and began to draw talismans to strengthen the seal according to the method passed down by his ancestors.

When the demon general saw that Kai dared to attack, a trace of anger flashed in his eyes, and he swept the giant axe towards Kai’s waist.

Kai dodged like a ghost and at the same time summoned the Dragon-Slaying Sword. The golden sword energy fell on the demon general like raindrops.

However, the demon general had extremely strong defense, and the sword energy only left a faint white mark on him, causing no substantial damage at all.

“It’s useless! My demonic body is invulnerable to swords and spears. With your little ability, do you think you can hurt me?”

The demon general laughed arrogantly and swung the giant axe again, forcing Kai to retreat again and again.

Kai was anxious, he could feel that the demon general’s strength was recovering. If this continued, not to mention reinforcing the seal, both of them would die here.

At this moment, he suddenly remembered the magic dragon’s inner elixir and hurriedly took it out from his arms.

The inner elixir exudes a strong demonic energy, which may be used to temporarily suppress the demon general.

He injected spiritual power into the inner elixir, and the inner elixir instantly burst out with dazzling black light and flew towards the demon general.

When the demon general saw the inner elixir, a hint of greed flashed in his eyes and he reached out to grab it.

“Now!”

Kai seized the opportunity, and the Dragon-Slaying Sword turned into a stream of light and slashed towards the demon general’s arm.
